The tcp/ipv6 protocol suite is not installed by default on windows server 2022.

Resetting network settings in Windows is usually the last resort for dealing with complex issues with local network or Internet access. This feature allows resetting network and TCP/IP settings to their default values, removes and reinstalls all network adapters on a computer. Let’s look at how to reset network settings in Windows using a GUI and the command line.

Before you reset network settings, make sure that you have tried all typical network diagnostic tools: checked IP settings, switch/router/provider operability, updated network adapter drivers, restarted your computer, used the built-in Windows Network Troubleshooter tool (the command to run it: msdt.exe /id NetworkDiagnosticsNetworkAdapter ), etc. If neither of the methods helped you to fix the network issue, you can try to reset the network settings.

Save Current Windows Network Settings

When resetting network settings in Windows, you will lose all network settings you configured manually: IP addresses, static routes, network driver settings, saved Wi-Fi networks/passwords will be cleared, etc. Therefore, it is important to save your current network settings before resetting.

List network adapters:

Get-NetAdapter|select name,InterfaceIndex,InterfaceDescription,InterfaceOperationalStatus,MediaConnectionState,DriverInformation|ft

For all connected network adapters, check if they receive IP settings automatically (via DHCP) or manually:

Get-NetIPInterface -InterfaceIndex 7

If the interface value is Dhcp=Disabled, then the IP settings for the adapter are set manually and you have to save the current settings to a file:

Get-NetIPConfiguration -InterfaceIndex 7 >>c:\backup_network_settings.txt

Display and write down all static routes in the routing table (from the Persistent Routes section):

route print

Using PowerShell, display a list of configured VPN connections and write down their settings:

Get-VpnConnection

In my case, saved VPN connection settings were not reset. Also, the OpenVPN Wintun virtual adapter was not deleted (it is used to connect to an OpenVPN server).

List WLAN profiles and save Wi-Fi network settings to a file:

netsh wlan show profile
netsh wlan export profile name="WiFi2022" key=clear folder=c:\ps

Export Winsock settings:

netsh winsock show catalog > c:\winsock-backup.txt

After resetting the network, the information you have saved will help you to restore all network settings you configured manually.

How to Reset Network from Windows Settings?

In Windows 10 (1607+), Windows 11, and Windows Server 2019/2022, you can reset network adapters from the Settings panel. Go to Settings -> Network (or use a quick access command to open ms-settings: ms-settings:network). Click Network reset -> Reset now.

Confirm the reset. Windows will clear all network settings and remove network adapters (your network adapters will not be shown in the Control Panel). The network settings will be reset to the default ones. Windows will restart automatically in 5 minutes.

After the restart, Windows will detect all connected network adapters and install drivers. Then you just have to configure network connection settings and make sure that the problem is fixed.

Performing Network Reset in Windows Using CMD

You can also reset your network configuration in Windows manually using the command line tools.

Reset the DNS cache:

ipconfig /flushdns

Reset WinSock:

netsh winsock reset

Sucessfully reset the Winsock Catalog.

You must restart the computer in order to complete the reset.

This command resets settings in the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinSock2\Parameters. Previous WinSock settings are automatically saved to the Protocol_Catalog_Before_Reset key.

To reset TCP/IP v4 stack settings:

netsh int ip reset

To reset TCP/IPv6 stack:

netsh int ipv6 reset

Restart the computer to complete this action.

This resets the settings in the HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters and \SYSTEM\CurrentControlSet\Services\DHCP\Parameters registry keys.

Remove all network adapters:

netcfg -d

In order to reset Windows Defender Firewall rules run the command:

netsh advfirewall reset

Also, PowerShell has a separate command to reset the advanced settings of a specific network adapter. List current adapter’s settings:

Get-NetAdapterAdvancedProperty -Name Ethernet0|ft -AutoSize

Here you can display the settings of Jumbo Packet, VLAN, buffer sizes, etc.

To reset them, use the command below:

Reset-NetAdapterAdvancedProperty -Name Ethernet0

Restart your computer and configure all network settings again. If your computer is configured to obtain an IP address and network settings automatically from a DHCP server, you have nothing to set manually.
